Home Solar Cost Guide

What Indiana still offers after the federal credit ended

Every incentive on this page is verified against Indiana government sources - and the expired ones salespeople still quote are called out.

The 30% federal solar tax credit ended for installations finished after December 31, 2025 - Greendale systems completed in 2026 get $0 from it.

Under Indiana's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.

Installed home solar for Greendale homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.

If a salesperson in Greendale tells you a 30% federal tax credit applies to your 2026 installation, they are quoting a dead law. What may still exist: Indiana's own incentives and tax treatment, listed below, and lease/PPA arrangements where a company claims commercial credits - in which case the credit belongs to them, not you.

Leased and PPA systems deserve extra scrutiny in 2026: the sales pitch often bundles 'tax savings' that now accrue to the leasing company under separate commercial rules - not to you. Get every claimed saving in writing, attributed to a specific law, before signing a 20-25 year contract.

Indiana rules that decide your payback

RuleIndiana status
Export compensation (net metering)Retail net metering is closed to new residential customers in Indiana; a homeowner going solar in 2026 takes an "excess distributed generation" (EDG) tariff under which only the electricity that flows back to the grid (outflow, measured instantaneously against on-site use) is credited, at a commission-approved rate equal to the supplier's average marginal price of electricity during the most recent calendar year multiplied by 1.25 — well below the retail rate the customer pays for inflow.
State incentiveNo state-level incentive; utility rebates may apply
Sales tax on the systemNot exempt - taxed like any purchase

Netting is instantaneous rather than monthly — only power exported at the exact moment production exceeds household use earns the low EDG credit, so self-consumption matters far more than under old net metering; and any unused EDG credit balance is forfeited (passed back to other ratepayers) when the customer stops taking service at that premises.

What this means for Greendale roofs

Beware of any 2026 payback estimate that looks as good as the 2025 ones: with the federal credit gone, a third of the old subsidy math vanished. If a sales projection has not gotten noticeably worse since 2025, it is hiding something - usually an inflated utility-rate escalation assumption.

Getting Greendale quotes

Same-day contracts are a red flag in this industry. Legitimate IN installers expect you to compare bids, check licenses, and read the interconnection terms. Anyone pressuring you to sign at the kitchen table is pricing in your haste.

Common questions

How much does home solar cost in 2026?

The U.S. marketplace average is about $2.58 per watt installed - roughly $15,500 for a 6 kW system and $31,000 for 12 kW, before any state incentives. Quotes meaningfully above that level deserve a written explanation of what justifies the premium.

Do I need a battery with my solar?

Not necessarily. Under full retail net metering, the grid effectively stores your surplus for free. Batteries earn their $12,000-16,000 price where export rates are low, outages are common, or time-of-use rates make evening self-consumption valuable.

What is net metering and why does it decide everything?

It is the rule for how your utility credits electricity you export. Full retail net metering credits exports at the same rate you pay - the grid works like a free battery. Net billing or avoided-cost rules pay far less per exported kWh, which lengthens payback and strengthens the case for a home battery.

How do I check if a solar quote is fair?

Divide the total price by the system's wattage. The U.S. marketplace average is about $2.58 per watt installed; $2.30-3.00 covers most fair quotes depending on roof complexity. Above that, ask exactly what you are paying extra for - in writing.

Is my roof even suitable for solar?

Three things decide it: orientation (south-facing is best in the U.S., east-west workable), shade (trees or taller buildings across midday hours can sink the math), and roof age (if the shingles have under 10 years left, reroof first - removing and reinstalling panels later costs thousands). Any honest installer assesses all three before quoting a number.
